Title: Production of compositions containing finely divided metallic silver
IPC: C03C17/10
Filed: 1946-09-06
Abstract: Silver oxide is treated with a protein hydrolysis product of molecular weight at least 300 in the presence of an organic base stronger than ammonia which is free from halogen and thiol groups to produce a composition containing finely divided metallic silver having a major proportion of colloidal sized particles.  Proteins which may be hydrolysed to give suitable products include casein, gelatin and egg albumin.  The base is an alkanolamine, desirably diethanolamine.  Silver films are produced by applying the composition to the surface to be coated and heating preferably in the absence of oxygen.  Thinners such as ethylene and propylene glycols and their monoalkyl ethers may be added to the composition.  When applied to ceramics the usual fluxes-bismuth carbonate or lead borate-may be added.  The hydrolysis of casein is effected by dissolving in water heating to 70 DEG  C., adding caustic soda and heating to 90 DEG  C. for 3 hours whilst stirring. The solution is diluted with water, filtered, and the filtrate treated with 10 per cent aqueous nitric acid until no more precipitate is formed, the liquor decanted, and the precipitate well washed with water.  In practice, this product is treated with the base to form a salt before the silver oxide is introduced.ALSO:Non-metallic surfaces are coated with silver by applying a composition containing finely divided silver formed by treating silver oxide with a protein hydrolysis product of molecular weight at least 300 in the presence of an organic base stronger than ammonia such as an ethanolamine, which is free from halogen and thiol groups and then heating, preferably in the absence of oxygen.  Thinners such as ethylene and propylene glycols and their monoalkylethers may be added to the composition for silvering thermoplastic and thermosetting resins by brushing, spraying or printing, or fluxes such as bismuth carbonate or lead borate may be added for silvering ceramics.  Mica and polythene may be silvered by this process.ALSO:According to the first Provisional Specification, a medicinal preparation is prepared by mixing moist silver oxide, a protein material such as protalbinic acid and a water-miscible liquid or volatile basic organic material such as ethanolamine.

Title: A method of and apparatus for testing rubber mixtures during the process ofvulcanisation
IPC: G01N3/32
Filed: 1962-07-16
Abstract: 1,006,354. Testing vulcanisation of rubber. GUMIIPARI KUTATO INTEZET. July 16, 1962 [July 14, 1961], No. 27264/62. Heading G1S. The shear modulus and relaxation characteristics of rubber are tested as vulcanisation proceeds using a test sample 8 held round a disc 7 (Figs. 1 and 2) within a mould comprising two movable members, 1and 3, provided with a clamping screw 11 and heating pipes 13 to simulate the pressure and temperature conditions of the production process. The disc 7 is mounted on a shaft. 5 extending through the number 1 and is reciprocated rotatably by means of a leaf spring 15 which is fixed to the shaft 5 and hingedly convected via a lost-motion linkage with a rod 17 linearly reciprocated by a motor-driven eccentric 21. As the sample 8 hardens, the oscillation amplitude of shaft 5 is reduced (the spring 15 fluxing as its upper end follows the constant-amplitude motion of rod 17). An arm 22 rigid with shaft 5 is magnetically held in contact with the feeler of a dial gauge 25 the readings of which vary with the variation in shear modulus of the sample. The variation of shear modulus and relaxation may be recorded on a revolving drum 32 (Fig. 4) by means of a scriber 31 which moves with a rod 29 (reciprocated via a disc 27 in phase with, but with greater amplitude than, rod 17) and which is pressed into contact with the drum by an electromagnetically urged arm 34 whenever contact exists between the arm 22 and either of switch contacts 35 adjustably set a predetermined distance apart. Thus the angular movement of the arm 22 is fixed and is smaller than that of the upper end of spring 15 which continues to flex while the arm 22 is held stationary against a contact 35. During this period the scriber will mark a trace a-b (Fig. 5), the arm 35 receiving an increment of rotation at the end of a stroke of the rod 17. On the reverse movement of the latter, dependent on the relaxation characteristic of the sample, arm 22 will not leave the contact 35 until spring 15 has passed beyond the position at which contact was made (the point "a") giving a trace c-e of longer length than a-b. The difference between the two curves, A and B, enveloping the ends of the traces gives the variation of the relaxation characteristic during the vulcanisation process; the curve A shows the behaviour of the shear modulus.
